I think this is referring to the fact that React uses synthetic event listeners - it's cheaper to bind an event listener once at the root and do your own element matching than it is to continuously bind and unbind listeners.

> React doesn't provide a way to explicitly bind to properties and events of DOM elements

We can nitpick this point because react has had a ref API for at least 5 years now. Given a ref, all DOM API are available. For events, SyntheticEvent will refer to a native event if it exists.

The SyntheticEvent abstracts vendor discrepancy. Under the hood, react can apply some optimization too.

The synthetic event also adds its own abstractions though. For example, the `onChange` handler in React behaves very differently to the native DOM `change` event.

And then some. Switching to react-native or other render targets can also be a doozy. Hopefully the references clarify all the features.
